Abstract
An electrically conductive support for use in an electrophotographic photoreceptor includes a cylindrical main body having a first end and a second end opposite to the first end in an axial direction of the main body. The main body contains an aluminum alloy and has an internal stress in a range of −30 MPa to 5 MPa. A method of producing the electrically conductive support includes preparing a substrate containing an aluminum alloy obtained at least through an extrusion step, and heat treating the substrate to obtain the electrically conductive support. The heat treating is carried out such that, when a temperature of the heat treating is defined as T (° C.) and a time of the heat treating is defined as H (hours), an amount of the heat treating Q defined by Q=T×H is 800 or less.
